Hi @saeedmiri,
PHP notices are naturally soft errors so shouldn’t be causing any issues with your site or messages that are visible to site visitors at any point. I will still pass this on to the development team to see if there is any requirement for the variables to be declared by us or whether this is happening because something else in WordPress should be defining them and is being loaded out of order.
Thanks,
Peter.
